Colic remains one of the most frequent and costly causes of equine morbidity and mortality, with significant welfare and economic implications. Disturbances in the gut microbi-ome are increasingly recognized as an important contributing factor. In recent years, prebiotics, non-digestible substrates that promote beneficial microbes, have emerged as promising microbiome-targeted strategies. Akkermansia muciniphila (A. muciniphila) has gained attention for its unique ability to degrade mucin, maintain epithelial integrity, and exert potent anti-inflammatory effects. Although its benefits are well established in hu-mans and rodent models, little is known about its abundance, function, and therapeutic potential in horses. This review evaluates current evidence on prebiotics and A. mucini-phila in equine gut health and outlines their translational potential by examining biological mechanisms, feasibility of therapeutic application, and implications for equine colic prevention. Importantly, this review is intended as a hypothesis-generating synthesis rather than evidence of causality. Proposed mechanisms and therapeutic implications are based primarily on extrapolation from non-equine models and limited equine observational data, highlighting critical knowledge gaps and the need for controlled, hypothesis-driven studies in horses.
